Answer: Option C is correct!
Step-by-step explanation:
The range of function is [-1,-5] . so first option is incorrect.
Since graph of the function f(x)=-2sin(x) is shifted down by 3 because of -3
therefore option B is incorrect.
Period of the given function is 2pi because here b =1 and period of sinx function is given by [tex]\frac{2\pi }{b}[/tex] therefore option D is also incorrect
Period of the function f(x) is always absolute value number in front of sinx which is given to be 2 here therefore option C is correct.!
